Fix rate control algo reference leak in case if network device has been
failed to register.  In this case special flag priv->mac80211_registered is
not set and the rate algo reference is not freeing on module unload.  That
leads to OOPs in further ieee80211 rate register/unregister procedure (by
any callee).

It should fix the bug #9470

Shaddy Baddah found an alignment problem with zd1211rw driver at
2007-11-19. This patch fixes it, it is based on the patch proposed by
Herbert Xu. The alignment 4 has been the agreed value on the
linux-wireless mailing list.

Notify that the problem does only affect the old zd1211rw softmac
driver and not the zd1211rw-mac80211 driver. Daniel Drake has
already provided a patch for the replacement of the softmac
driver, which this patch will break.

lbs_mac_event_disconnected() was called once and then never again
upon a hardware MAC event.

The reason was that the driver didn't clean the correct bit in the interrupt
cause register of the chip.

I'm not sure why it was doing this, and I'm not sure I _want_ to know
why. But calling it NETIF_F_DYNALLOC doesn't change the fact that the
kernel believes it to be NETIF_F_IPV6_CSUM, and that IPv6 communication
is hence buggered.

The interrupt handler returns IRQ_NONE if it detects that the device
is gone. That's incorrect because the device may have raised the interrupt.
Not acknowledging it may trigger the spurious interrupt detection and kill

The validation of the chipset revision was broken
since for rt2500usb and rt73usb different registers
should be read. When rt2500usb was loaded for a rt73
device it would false think the chipset was correct
because the wrong register was read and validated.

This has been fixed by expanding the check to also
see if the first 4 bits of the revision is not-0
(When reading the wrong register offset the returned
value is usually 0 which can be interpreted as invalid)

Prior to this patch, iwlwifi would always use the first
registered rate control algorithm which, depending on system
setup, could be anything. After the mac80211 patch to make
the simple algorithm built-in, it would always be simple.

This has always been a bug in iwlwifi.

This fixes it by requesting that mac80211 selects the right
rate control algorithm.

Fix an IRQ race condition in b43legacy. If we call
b43legacy_wireless_core_stop(), it will set the status of the device to
INITIALIZED and the IRQ handler won't care any longer about IRQs, thus the
kernel will disable the IRQ if it's shared (unless we boot it with the
'irqpoll' option). So we must disable IRQs before changing the device
status.
